scams. 01.111-9) My invention consists in a new and useful improvement in dish washers, and is designed to provide a device for washing dishes which providesthe washing apparatus as a part of the table upon which the dishes are used. The particularly novel and useful feature of my device is the combination with the washing apparatus of means for removing the dishes from the table to the washing chamber. My invention has also many novel and useful features in the mechanisms which I provide for treating the dishes'in the washing chamber, among which are the means is to be.v distinctly understood that I do not consider my invention limited to said specific embodiments, but refer for its scope to the claims appended hereto.

Fig. 10 is a section on the line |'-|0 of Fig. 9.

Fig. -11 is a section on the line of Fig. 3. .As illustrated in" the drawings, my device consists of a substantially circular table having the fixedtop portion I, to which are attached the extensions 2. 2, a centrally disposed annular base 3 on which is mounted the annular wall 4 upon which is received the circular top 5. The portions I, l are mounted upon the outer wall and the inner wall I. i

A storage cabinet C which serves as a conveyor is disposed between the inner wall "I and the annular want, and the dish washer H is disposed between the outerwall 5 and the inner wall I, at the point indicated in Fig. 1. p I will now describethe construction of the cabinet 0 (illustrated in Figs. 1, 2 and 8). Suit-- .ably mounted in the base 3 there are a plurality of tubes 20|, one being shown enlarged in Fig.

8, in each of which there is slidably mounted a tube 202 having a piston head 203 thereon. A conduit 204, to conduct compressed air to each of the tubes 202 to operate its piston head 203, is suitably provided. Integral with each head 203 there is a finger 205, and depending from these fingers 205, there is a cylindrical; hanger 206 15 carrying at its bottom three annuli 201 so disposed as to form a trackway 208 in which is slidablymounted a shoe 209 carrying thereon the cylindrical frame 2 0 of the conveyor and storage cabinet C, to which is attached the annular top 2 and annular shelves 2|2, 2|3 and 2H.

Suitably mounted for rotation upon the base 3 there is the pulley 2|5 which is connected by the belt 2|6 with, any suitable prime mover, as for example, the motor M. Suitably mounted upon the pulley 2| 5 there is the post 2| I received in the telescoping sleeves 2 I8 and 2|9 carried by the frame c2|0, constituting means for rotating the storage" cabinet C. I will now describe the construction of the dish washer. H (illustrated in Figs. 1, 2 and 3). At the point indicated by the reference character H in Fig.1, I provide an insulated chamber 50| having the vertically movable cover 502 which is made integral with the shelf K which it oper- 5 ates. Thiscover 502 is mounted on three elevators 503 which are similar in'construction to the elevating means provided for'the cabinet C heretofore described. The chamber 50| has the partition 504 formed as will be present explained 40 near its bottom forming the heating chamber 505 in which are positioned the electric heating coils 506 and into' which discharges the water supply pipe 501. Directly above the partition 504 there'are the manifolds 508 .conected by the series of pipes 509, the spaces between which are filled with any suitable material to form the partition 504. Each pipe 509 has in its upper surface openings 5| 0. Passing through the partition 504 and connecting the heating chamber 505 with one of the manifolds 508 is the pipe 5| with the check valve 5|2. To one of the manifolds 508 there is connected the water supply pipe 5|3, and to the other manifold 508 there is connected the compressed air supply pipe 5. The chamber is supplied near its bottom with the controlled vent 5l5 and near its top with the overflow vent 5! 6 adjacent which is the discharge opening 5!! controlled by the slide valve 5l8 operated by the handle 5!9 passing through the wall-6. I provide a wire dish rack 520 which when inverted and attached to the hook 52! serves as an incline for receiving dishes into the washer H, over the inclined lip 522 below the opening 523 of the washer H, which registers with the shelf 2! 2 of the conveyor 0.

Pivotally mounted on the fixed top portion I adjacent the opening 523, there is the arcuate baflie plate 524 with facing plate 525 of rubber or any suitable material, corresponding with the circumference of the conveyor C and normally beneath the top 502 closing the opening 523. This plate 524 has the crank arm 526 to which is attached the operating rod 52'! having the handle 528 suitably positioned in the wall 6 and the spring 529 to hold the plate 524 in normal position. Below the shelf K and adjacent the open top of the chamber 50! of the dish washer H, I provide a dish assembly drain board 530 inclined toward the chamber 50 I. p

I will now describe the construction of the form of the dish washer H illustrated in Figs. 4, 5, 6, and 7. I provide the chamber formed by the side walls 602 and 605, the front wall 604 adjacent the main outer wall 5, the rear wall 605, and the bottom 606 spaced from the floor upon which my device is placed, and the movable top 60'! which is carried upon two elevating means, the construction of which I shall now describe. Suitably mounted upon the floor beneath the chamber 60!, there are two tubes 505 rising through the bottom 606 to the top 50! of the chamber 50!. In each tube 500 there is slidably mounted a tube 509 closed at its'upper end by a head M0, on which the top 60! is mounted .and from which depends a sleeve 5!! surrounding the tube 608 and so proportioned as to extend from the top 50'! to the bottom 505, when the parts are in normal position. Diimosed v in each tube 505 and passing upwardly inside of the tube 500 is the compressed air supply pipe 5 l2 having its upper end 6l3 close-' ly adjacent the head 6l0 when the parts are in normal position (illustrated in Fig. 6) The pipe N2 passes through a plug 5!4 closing the lower end of each tube 500 which is filled with oil to a point closely adjacent the upper end 5! 3 of the pipe 5!2. Each tube 505 is provided at its lower end with an interior collar 5!5 forming a reduced passage 5!5 about the pipe N2, and having a leather washer 6!! to form a leak-proof joint between the tube 608 and the tube 509. The two pipes 5l2 are connected with the pipe 5l5 having the control valve 5!! with operating handle 620 suitably mounted on the outside of the wall 502.

It is to be noted that in Ilg. 6 I have illustrated the application of one of the above described ele-' vating means to the cabinet C, in which the heads 6!0 have the fingers 205.

Attached to the lower ends of the sleeves 5! I, there is the frame 52! having the cross bars 62 !-A, on which is carried the basket B. Suita bly mounted on the frame 52! there is the dish slide 622. The upper end of this slide 522 is posi-' tioned closely adjacent the upper edge of the rear wall 605 of the chamber 50!, when the parts are in normal position, thiswall 505 being spaced from the top 50! of the chamber 50!, to register with the shelf 2!2 of the cabinet C and form the opening 625 in the dish washerH, so that dishes may be delivered from the cabinet'C into the dishwasher H. Below the dish slide 02: there is the rack 624 for the refuse receptacle 625, and suita-' bly attached to the underside of the top 50'! there is the wiper 626. The rack 624 has a wire mesh bottom 624-A upon which glasses or other articles may be placed by hand for washing, when the refuse receptacle 625 is removed.

Upon the bottom 506 of the chamber 60!, I -provide a perforated coil 62! connected with the air supply pipe H8 and having the control valve 620 with operating handle 629 suitably mounted on the outside of the wall 602.

' Suitably disposed, between the valves 5! 9 and 628,1 provide the hot and cold water pipes 550 and 63! with valves 632 and 533 respectively connected with the common discharge pipe 534 passing through the wall 602'to the interior of the chamber 80!.

I provide a waste vent 536 with discharge pipe 631, and any suitable form of control valve 555 with operating handle 639. Suitably mounted on the wall 602, I provide an overflow 540.

I will now describe the use and operation of the conveyor and storage cabinet C. It is to be understood that any suitable form of manuallyoperated control mechanism for the elevating means 20! and 202 of the storage cabinet C and any suitable form of manually-operated control mechanism for the motor. M are provided. By the proper operation of the elevating means 20! and 202 the degree of lift of the frame 2!0 may be so controlled as to cause any one of the shelves 2!2, 2|3 and 2 to register with the horizontal plane of the top portions when the parts are in the position indicated in dotted lines in Fig. 2, or in lower adjusted similar positions, the

operator by supplying energy from'the motor M may cause the conveyor C to rotate clockwise, as indicated by the arrow in Fig. 1. Attention is called to the fact that the shelf 2! 2 provides a continuous annular space between it and the cover 2! When the shelf 2 2 is caused to register with the top portions this space is accessible to nipulation of the rod 521 by its handle 525, they baflie plate 524 is caused to move from its normal position, across the shelf 2 2 until the outer end of the facing plate 525 contacts the surface of the frame 2 0. It is obvious that when the baffle plate 524 is in this position and the conveyor C is caused to rotate, the battle plate 524 will remove any article upon the shelf 2l2 causing it to pass through the opening 525 into the chamber 50! of the washer H. Attention is called to the fact that when the baffle plate 524 is in the above described position, the conveyor C cannot be moved verti cally. After one complete rotation of the conveyor C all of -the articles having been removed by the baffle plate 524, by reason of such rotation, thebame plate 524 is returned to normal position by the action of the spring 525, when the rod 52! is released by the operator.

I will now describe the use and operation of the dish-washer H, as'illustrated in Figs. 1, 2 and 3. It is to be understood that any suitable form of manually operated control means for the water supply pipe H8 is suitably positioned. By this means water may be supplied through the pipe m, the manifold m and pipes, m to an the chamber 50I to the level of the overflow 5|0.

- onto the inclined bottom of the wire rack 520 and are thus directed toward the bottom of the chamber 50l. -When it is desired to complete the washing operation, the operator by means of any suitable manually operated control means for the vent 5I5 can evacuate the water from the chamber 501. The cover 502 is then raised by the operation of the elevating means 503, through the manipulation of any suitable. form of manually operated control means. The dishes. in the chamber 50l are then removed by hand to the dish-assembly drain board 530. The rack 520, disengaged from the hook 52l, may also be removed to the board 530. The dishes areplaced properly in said rack 520, which is then placed on,

the bottom of the chamber 50!. The top 502' is then returned to normal position. The vent 5|5 having been closed, hot water is supplied to the.

chamber 50l through the pipes 509, by the operation of the heating chamber 505. At the same time compressed air from the pipe 5 may be caused to pass through the pipes 509 into the chamber 50l, aerating the water therein to assist the washing operation. Shortly after applying the bath to the dishes the slide valve 5l8 may be opened by pulling the handle 519, thus opening the discharge opening 5" to cause removal from the dish washer H of any refuse matter. After the washing operation has been completed the wash water may be evacuated through the vent H5 and compressed air supplied through the pipe 5 and the pipes 509 to cause a draft through the chamber 50l escaping through the openings SIB and 5H, to dry the dishes. The top'502 may then be raised and the rack 520 carrying the clean dishes may be-removed to the shelf 530,

and the dishes removed from the rack 520 may be placed upon the top 2 of the conveyor C and therebyconveyed to any desired point.

I will now describe the use and operation of the form of dish washer H, illustrated in Figs. 4. 5,

6, 7 and 8. By the proper manipulation of the valves 632 and 633 the chamber may be filled with water to the water line W (Fig. 6) through the discharge pipe 634, which water may be at the desired temperature. The dishes P are caused to move from the shelf 2| 2 of the conveyor C, as above described, entering the dish washer through the opening 623 and being received upon the slide 622. As each dish passes over this slide 622, the wiper 626 removes from the dish any refuse that may be thereupon, which refuse, falling, is received in the receptacle 625. Attention is directed to the fact that each dish P being directed into the water in the chamber 60l by the slide 622, takes the course indicated by the illustrations of the dishes P in dotted lines, and arrows, in Fig. 6, until each dish P settles into the basket B upon the bottom 606 of of the shelf m, for the removal'of the washed dishes.
